LANTERN.

SPECIFICATION forming part of Letters Patent No. 717,346, dated December 30, 1902.

Application filed August 8, 1901. Serial No. 71,320. (No model.)

the lantern, and. thereby exposing the flameto direct air-drafts. It consists in the construction and arrangement of the frame and in various details of construction, which will be hereinafter fully enumerated.

My invention will be more clearly understood by reference to the accompanyingdrawings, in which Figure 1 illustrates avertical section of my improved lantern on the linel 1 ofFig. 2. Fig. 2 represents a horizontal section on line 22 of Fig. 1. .Fig. 3 shows a detached perspective view of the upper ring constituting a portion of the frame surrounding the chimney. Fig. 4 illustrates a modification of the oil-reservoir, in which case the outer casing is fixed and the oil reservoir is movable, the

arrangement being the reverse of that illus-' trated in Figs. 1 and 2; and Fig. 5 is a do tached perspective view'of a portion of thelower ring of the frame, showing one of the vertical ribs about to be placed in position.

Referring to the reference-letters of the drawings, A represents the oil-reservoir, B the burner, and O the chimney. The oil- I reservoir, as shown in Fig. 1, is fastened to a casing A, which in turn is connected to the base A casing A is a movable casing A which is supported upon the base A by a head a and which may be turned by passing the fingers through the openings ctin the casing A. At the top of the movable casing A is a circular rack A which is adapted to engage the pinion b on the stem 1), which latter is adapted to raise and lower the wick W through the medium of toothed wheels 6 19 on the stem 1). Arranged above the base A is a casing A provided with a series of air-inlet openings a and within this casing and separated therefrom by an annular space is a Between the oil-reservoir A and easing A, at the bottom of which is arranged a series of air-passages a admitting air from the ann ular space between the casings A and A into an annular space formed between the casing A and the movable casing A By the arrangement just described the air admitted to the burner is caused to follow a winding path, which breaks the force and prevents a direct draft reaching the flame. I Surrounding the chimney C is a frame D, comprising an upper ring D and a lower ring D united by vertical .ribs D which are stayed by a central ring D.

The ribs D are provided at the bottom with projections 61 above which are slots 61 The ends of the ribs are placed in slots d in the ring D and the ends d of the ribs after being passed through openingsin thecasing A are bent upwardly against the back of the ring'D The upper ring D is provided with a series of openings (1 to receive the upper reduced ends of the ribs D The ring is also provided with projecting ears Dfiwhich form an integral part of the ring and are bent downward and upward in the form of a loop, the ends of which are provided with openings 61 to receive the bail or handle D Above the ring D and surrounding the top 1 of the chimney G is the hood E, comprising- "reservoir F, which carries the burner F, is

supported upon a base F which carries an outer casing F provided at the top with a rack j, which engages a pinion f on the wick-operating stem J.

In the form shown in Fig. l the raising and lowering of the wick are accomplished by turning the casing A while in the modified structure shown in Fig. 4 the outer casing F is stationary, while the reservoir F is revoluble for the purpose of raising and lowering the wick.

The engagement and disengagement of the pinion f from the rack f when desired for the purpose of changing the wick or replenishing the oil in the oil-reservoir are conveniently and easily effected by the user holding the burner with one hand while with the other hand the oil-cup is revolved until the engagement or disengagement, as the case be, of said parts is effected,which operation prevents movement of the wick, while at the same time it effects the separation of the parts.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a lantern, the combination of two casings or cylinders, and one thereof adapted to be rotated around the other; one of said casings being adapted to contain oil and supportinga burner provided with a wick-raising spindle having a pinion on its outer end, and the other of said casings having a circular rack formed on its upper end and adapted to engage with said pinion and to remain in engagement therewith when the burner is in position, as and for the purpose set forth.

2. In a lantern, a removable base supporting two casings or cylinders, one of said casings being adapted to be rotated around the other; the inner one of said casings supporting a burner having a wick-raising spindle with a pinion on its outer end; the outer one of said casings having a circular rack formed on its upper end adapted to engage with said pinion and to remain in permanent engagement therewith when the burner is in position, as and for the purpose set forth.

3. In a lantern, in combination with a removable base, a frame composed of two rings connected together by vertical ribs, the lower ends of said ribs being grooved and adapted to engage with corresponding grooves formed in the lower ring, and having also projecting ends bent upwardly against the inner side of a casing interposed between said projecting ends and said lower ring to secure the ribs and ring to each other, as and for the purpose set forth.

4. In a lantern, in combination with a removable base, a frame comprising an upper and lower ring connected together by vertical ribs, the upper one of said rings having curved extensions formed integral therewith provided with openings for the reception of the bail, and the lower one of said rings having slots or grooves formed therein for the reception of corresponding slots or grooves formed in the lower ends of said vertical ribs, as and for the purpose set forth.

5. In a lantern, the combination of a frame comprising upper and lower rings formed of metal, connected by vertical ribs, and a removable base adapted to be supported in and by said frame, said upper ring being composed of a single piece of metal provided with spaced openings, and having perforated curved extensions integral therewith, said spaced openings being arranged to receive the reduced upper ends of the aforesaid ribs, the lower ends of which interlock with the lower ring, substantially as set forth.

6. In a lantern, the combination of a frame comprising an upper and a lower ring connected together by vertical ribs, the lower one of said rings having slots or grooves formed therein for the reception of corresponding slots or grooves formed in the lower ends of said ribs, and having also a circular flange formed on its inner side, and a removable base adapted to be supported in and by said frame, as and for the purpose set forth.

7. In a lantern, in combination with the chimney and frame surrounding same, ahood, comprising an outer casing extending above the chimney and hav ing a series of openings near its top, an inner casing or shield placed and supported adjacent to the said openings in the outer casing, said inner casing being imperforate and being closed at its upper end, and a conical ring supported by the chimney and extendinginto saidinner casing or shield, as and for the purpose set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

JOHN T. CASEY.
